A TAC MENT FOR W D W?? a Ap ication'mea commit-10,1923;seria m'.661 758;aenewerrqiine iaf192a 1 7 "My present invention relates generally to" attachments for windows and more partic-' ularly to a storm sash fasten er my object. of a simple lDGXPBHSIVB 5 arrangement which will be effective andlefli-- being the provision cient' in use for the usual and intended purposes I cially in the open position of the storm sash as well as proof against accidental displace- Inflthe accompanying drawings which illustrate mypresent invention and form a part of this specification, f v V Figure 1 is a vertical section through a 15 window frame provided with a storm sash and showing thelatter open with my im-j proved fastener in effective position, p Figure 2 is an enlarged side view of a portion of the storm sash with my improved fastener, Figure 3 is a'detail face view of the storm sash bracket,

Referring now to these figures and particularly to Figures 1, 2 and 6 Ihave shown a window frame generally indicated at 10, to the upper outer portion of which the upper end of astOrmsash 11 i'shingedly mounted" as at 12. This storm sash closes against the outer surface of the window frame and is adjustably held in open po'sition by means tion includes a latch arm 13,1 storm sash bracket 14 and. EtWlIldOW frame keeper 15 associated together and'cooperating inthe particular manner which I will now describe. The-storm sash bracket 14 as seen partie ularly in Figures 2, 3 and 6 is' a, vertically elongated plate having upper and; lower apertures 16 for the reception of screwsand like fastening members 17 by which-to'secure' the same fiatwise against the inner surfaceof the storm sash at one side of the latter, this 9 plate having at one side an angularlyout-' standing ear 18 and also having'upper and lower. slotted apertures 19 andQO; I

end ofits opening 19, and. thus creates I a tension whichpressesithe lower edge of the latch arm more and more tightly against the upper edge of. the keeper strip as the storm sash is moved outwardly;

Adjacent to its free end the lower'e'dge of thelatch' arm '13-has a series of notches 27 withv taperingsidesand it is thus obvious that the tension on the latch arnicreated in the aboveinanner will serve to securely hold this latch arm in the fastened-positionwhen anyone of its notches comes into position over the edge. Not onlyis thist-rue but-,a.t[ the same time thetensionthus created on the latch arm will hold the same against rattling and in such manner as to avoid all danger of accidental displacement. I claim':. V
